ATI Pharmacology Proctored Exam 2023 Quizlet
1. While providing an Angiotensin-converting enzyme (ACE) inhibitor, the patient asks what the action of the drug is. As a healthcare provider, you explain that the action of an ACE inhibitor is:
- A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II
- B. To inhibit reabsorption of sodium back into the body, ultimately increasing urine output and lowering blood pressure
- C. To decrease heart rate and blood pressure by competing with Beta1 and Beta2 receptors in the heart and lungs
- D. To lower blood glucose by stimulating the release of insulin
Correct answer: A
Rationale: ACE inhibitors lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II. Angiotensin II is a potent vasoconstrictor, and by inhibiting its formation, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload on the heart. Choice B is incorrect as it describes the mechanism of action of diuretics, not ACE inhibitors. Choice C is incorrect as it refers to the action of beta-blockers, not ACE inhibitors. Choice D is incorrect as it describes the mechanism of action of antidiabetic medications, not ACE inhibitors.
2. A client has a new prescription for Prednisone. Which of the following instructions should be included in the discharge teaching?
- A. Increase your intake of potassium-rich foods.
- B. Avoid consuming grapefruit juice.
- C. Take this medication with food.
- D. Decrease your intake of sodium-rich foods.
Correct answer: A
Rationale: The correct answer is A: "Increase your intake of potassium-rich foods." Prednisone is associated with potassium depletion, making it important for clients to increase their intake of potassium-rich foods to prevent potential imbalances. Foods such as bananas, oranges, and spinach are good sources of potassium. Choice B, "Avoid consuming grapefruit juice," is not directly related to Prednisone use. Choice C, "Take this medication with food," is a general instruction for many medications but not specific to Prednisone. Choice D, "Decrease your intake of sodium-rich foods," is not directly related to Prednisone's side effects.
3. A client with renal failure and an elevated phosphorus level is prescribed aluminum hydroxide 300 mg PO three times daily. For which of the following adverse effects should the nurse inform the client?
- A. Constipation
- B. Metallic taste
- C. Headache
- D. Muscle spasms
Correct answer: A
Rationale: Correct. Aluminum hydroxide is known to cause constipation as a common side effect. Instructing the client about this potential adverse effect is important for their awareness and management. The other options, metallic taste, headache, and muscle spasms, are not typically associated with aluminum hydroxide use. Therefore, the nurse should focus on educating the client about the increased risk of constipation and provide guidance on managing this side effect to improve the client's comfort and treatment adherence.
4. A client has a new prescription for Timolol. How should the nurse instruct the client to insert eye drops?
- A. Press your finger on the inside corner of your eye for 1 minute after application.
- B. Apply the eye drops directly to the cornea.
- C. Drop the prescribed amount of medication into the center of the conjunctival sac.
- D. Wipe your eyes gently with a tissue immediately after application.
Correct answer: C
Rationale: When administering eye drops, it is essential to instruct the client to drop the prescribed amount of medication into the center of the conjunctival sac. This technique helps ensure proper distribution of the medication and reduces the risk of potential adverse effects. Pressing on the inside corner of the eye is done to prevent systemic absorption, applying drops directly to the cornea can cause irritation, and wiping the eyes after application can lead to decreased effectiveness of the medication.
5. What is the antidote for copper toxicity?
- A. Glucagon
- B. Aminocaproic acid
- C. Atropine
- D. Penicillamine
Correct answer: D
Rationale: Penicillamine is the specific chelating agent used for copper toxicity. It forms stable complexes with copper, which are then excreted in the urine. Glucagon is used for treating hypoglycemia, aminocaproic acid is used to treat bleeding disorders, and atropine is used as an antidote for certain types of poisoning, such as organophosphate toxicity.
